CONNECTIQNYOF UMBRELLA RIBS AND STRETCHERS.

1 '0 all whom may concern Be it known that I, SAMUEL S. F RETZ, S12,

a citizen of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulConnection of UmbrellaRibs and Stretcher-s, of which the following is aspeci-v fication. 7 p

- My invention consists'of novel connec ion for a rib and stretcher ofan umbrella (or parasol) of U or channel shape, the same embodying aplate adapted to straddle the rib and close around the same so as totake firm hold thereof and be prevented from slipping in any directionon the rib, it being adapted to receive the pivot which comprises theaxis of the stretcher and serves to retain the connection closed tightlyon the rib, the stretcher being mounted on said pivot on the exterior ofthe connection admitting of the stretcher folding over said rib withfreedom and closeness.

The invention is satisfactorily illustrated in the accompanying drawing,but the important instrumentalities thereof may be varied, and soit isto be understood that the invention'is not limited to the specificdetails shown .and described, as'long as they are within the spirit orscope of the claims.

Figure 1 represents aperspective view of a connection for an umbrellarib and stretcher embodying my invention.

Figure 2 represents a section thereof on line 22 Figure 1. I

Figure 3 represents a plan View of the connection embodying theinvention.

Figure 1 representsa section on line 44 Figure 3.

Figures 5, 6, 7, 8, 9, 10 and 12 represent various embodiments of ribsto which the connection is applicable Figure 11 represents a plan viewof .another embodiment of the connection.

Figures 13-18 inclusive represent views of other connections embodyingthe invention.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings.

1 designates a portion of a U-shaped umbrella rib. 2 designates aportion of a U- shaped stretcher therefor, and 3 designates a memberforming a connection for the stretcher with the rib.

Specification of Letters Patent.

'Application filed April 27, 1921. Serial No. 465,010.

Patented Feb. 7, 1922.

portions of the former are depressed and so reduced in. cross sectionproducing the neck 211, the terminals of which form the shoulers 5.

The connection 3 consists of a plate ofsuit-' able metal bent-intosubstantially sleeve or U-shape adapted to straddle and embrace the neck4 between the shoulders5 and having its end edges adapted to engage thelatter. On the inner terminals of the piece are lips 6 which areinturned and approach each other on the inner side of the rib and soclose said plate .at the inner side of the neck 4 whereby the connectionenvelops said neck.

In the sides of the plate adjacent to the lips 6 are openings 7 in whichare received the pin or rivet 8' whose ends are suitably headed andwhich forms the axis of the the longitudinal direction thereof.

The number of necks and consequently of the shoulders thereof may beincreased, as in Figures 6 and 7 while in Figure 8, the neck is of ashorter length than in figure 5,

the neck and shoulders are dispensed with,

but the connection with its lipsis applicable to the latter.

In Figure 10, the sides of the neck 4 are somewhat separated, while inFigure .15 the sides are closed and in contact. In Figure 11, theconnection is somewhat foreshortened from what is shown in Fi re 3.

In Figure 12, the back of the rib is formed with swell 9 which isadapted to receive the swell 10 on the back of the connection and thusinterlock the connection with the rib on theback of the latter, seeFigure 15, the same result being obtained by substituting the opening 11in the back of the connection for said swell 9, see Figures 16 and 17,the wall of said opening 11 being adapted to receive. the swell 9, seeFigure 18, thus in eithervcase interlocking theconnection with the rib,and preventing slipping of the same around the rib or in longitudinaldirection thereof. v

It will be seen that the ears of the connection are on the exterior ofthe connection and the stretcher may fold its entire length flat overthe rib.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is V 1. A connection for a U-shaped umbrellarib and a stretcher, consisting of a comparatively U-shaped memberadapted to straddle the .rib at the place of the joint of the stretchertherewith, and have the stretcher mounted thereon, said U-shaped memberhaving inturned portions forming a comparatively closed inner side and apivot adapted to form the axis of the stretcher, said pivot passingthrough the sides of said member close to the inner side of the rib.

' 2. In a connection for a U-shaped um-.

brella rib and a' stretcher, a comparatively U-shape member adapted tostraddle a de pressed part of said-ribat the place of the joint ofthestretcher therewith and to have the stretcher mounted thereon, theterminals of the sides of the member having lips in turned towards eachother on the inner side of the rib, and a pivot adapted to form the axisof the stretcher passing through the said sides of the member close tothe inner side of the rib and in close proximity to said inturned lips.
